A few years ago, my husband and I were on our way home from a trip down South, and we stopped in St. Louis in the late afternoon. The people sitting on the steps are literally in the shadow of the Gateway Arch, which extends out onto the surface of the river.
A dragonfly posed on the dock where I was sitting, on a lake in northern Wisconsin.
Last week we went to the Museum of Science and Industry in Chicago, which had an exhibit of old-fashioned bicycles.
